The subject 90 is loaded on the table 31. The subject 90 is loaded on the table 31 so that the long direction of the table 31 and the direction between the head and the foot of the subject 90 are the same direction. Here, referring to FIG. 1, the long direction of the table 31 denotes an X-direction. Further, the direction toward to the heard of the subject 90 denotes X1-direction, and the direction toward the foot denotes X2-direction. Further, the short direction (direction from right to left direction of the subject 90) of the table 31 orthogonal to the X-direction denotes the Y-direction. Further, When the subject is lying on the back thereof, the direction toward the right hand of the subject 90 denotes Y1-direction, and the direction toward the left hand of the subject denotes Y2-direction. Further, the orthogonal direction to both X-direction and Y-direction denotes the Z-direction. Further, the direction upward denotes Z1-direction, and the direction downward denotes Z2-direction. The table moving mechanism 7 a allows the table 31 to move in the X-direction, Y-direction and Z-direction while the subject is being loaded.

The display unit 32 displays an X-ray image 10 of the subject 90. The display unit 32 includes such as a liquid crystal display monitor.

The control element 60 is configured software-wise to be a functional block brought into reality by that the processor 6 a executes a variety of programs. The control element 60 can be configured hardware-wise by installing the exclusive processor (process circuit).

According to the present Embodiment, the control element 60, wherein the control element performs a control in which the information element 5 informs that a second imaging equipment component member 3 b moves when performing one control of the move of the first imaging equipment component member 3 a based on a first operation input to move the first imaging equipment component member 3 a among the plurality of imaging equipment component members 3 and another control of the move of the second imaging equipment component member 3 b different from the first imaging equipment component member 3 a of the plurality of the imaging equipment component members 3 while interlocked with the move of the first imaging equipment component member 3 a. In addition, the first imaging equipment component member 3 a is a member moved by that the operator operates intentionally. Further, the second imaging equipment component member 3 b is another member moved while interlocked with the first imaging equipment component member 3 a due to the control that the control element 60 provides. The inventors illustrate an example according to the present Embodiment, wherein the first imaging equipment component member 3 a is the table 31 and the second imaging equipment component member 3 b is the C-arm 30. Further, the move in which the second imaging equipment component member 3 b moves while interlocked with the first imaging equipment component member 3 a means that the second imaging equipment component member 3 b moves due to the operation that allows the first imaging equipment component member 3 a to move. Specifically, the move in which the second imaging equipment component member 3 b moves while interlocked with the first imaging equipment component member 3 a means that the second imaging equipment component member 3 b also moves while the first imaging equipment component member 3 a is moving.

The memory element 6 b stores such as a variety of programs which the processor 6 a executes and an X-ray image 10 which the image processing element 61 generates. The memory storage element 6 b includes a non-volatile memory such as e.g., an HDD (Hard Disk Drive) and an SSD (Solid State Drive).

The C-arm moving mechanism 7 b is configured to allow the C-arm 30 to turn and shift in parallel. The inventors set forth the detail structure of the C-arm moving mechanism 7 b.

(C-Arm Angle)

The X-ray fluoroscopy imaging apparatus 100 is capable of imaging the subject 90 in the direction, in which the X-ray is irradiated obliquely relative to the subject 90 from one end (cranial) or the other end (caudal) in the longitudinal plane along the long direction (X-direction) of the table 31 on which the subject 90 is loaded referring to FIG. 2A, from an arbitrary combination direction of the respective directions of the right anterior oblique (RAO) direction, the front direction and the left anterior oblique (LAO) direction referring to FIG. 2B. In addition, referring to FIG. 2B, the C-arm 30 is not shown.

(Imaging Position)

Referring to FIG. 3, the relative position (imaging position) of the C-arm to the table 31 varies depending on an imaging region. Referring to FIG. 3, the respective arrow directions are the directions in which the C-arm 30 is inserted relative to the table 31, wherein the X-ray detector 2 positions at the tip side of the arrow, i.e., subject 90 side, and the C-arm moving mechanism 7 b positions at the rear end (opposite end of the tip) side of the arrow. The position in which the C-arm 30 is in place along the long side of the table 31 (X-direction) is defined as HOME position. Further, the position in which the C-arm 30 is in place obliquely as the direction thereof is toward the foot side (X2-direction) of the subject from the head side (X1-direction) of the subject 90 and is toward the subject 90 from the long direction (X-direction) of the table 31 is defined as MULTI position. Specifically, the MULTI position is the position at which the C-arm 30 is in place obliquely at the head side of the subject 90 from the center position of the table 31.

Further, the position in which the C-arm 30 is in place along the short side of the table 31 (Y-direction) toward the center from the side of the subject 90 at the top view is defined as SIDE position. Specifically, the SIDE position is the position at which the C-arm 30 is in place laterally (direction along the Y-direction) near the center of the table 31 in the long direction (X-direction) of the table 31. In addition, the position moved toward the foot side of the subject 90 from the SIDE position is defined as the PERI position. Specifically, the PERI position is the position at which the C-arm 30 is in place laterally at the foot side of the subject 90 from the center position of the table 31 in the long direction of the table 31 (X-direction). For example, when the imaging from the head to the chest of the subject 90 is conducted, the HOME position is applied thereto. Further, when the imaging of the lower leg is conducted, the PERI position is applied thereto. Further, when the imaging of the abdomen of the subject 90 is conducted, the MULTI or SIDE position is applied thereto. In addition, the respective positions of the HOME position, the MULTI position, the SIDE position and the PERI position define the facing direction of the C-arm 30 and the relative position between the C-arm 30 and the table 31 (the respective position coordinates of the C-arm 30 and the table 31).

(C-Arm Moving Mechanism)

Referring to FIG. 4, the C-arm moving mechanism 7 b includes an arm pedestal 70, a rotation mechanism 71 and the moving mechanism 72. Referring to FIG. 4, the rotation mechanism 71 rotates the C-arm 30 around the shaft line of a rotation shaft 11 extending in the long side (X-direction) of the table 31 which is the line connecting the head and the feet of the subject 90. Further, the rotation mechanism 71 allows the C-arm 30 to rotate in the circumferential direction 80 of the C-arm 30, wherein the line extending in the short direction, which is the right-to-left direction of the subject 90, (Y-direction) of the table 31 is the shaft thereof. Such as the rotation mechanism 71 includes e.g., a motor and so forth.

The moving mechanism 72 is installed to the arm pedestal 70. The C-arm 30 can be horizontally moved in accordance with the horizontal move of the arm pedestal 70 moved by the moving mechanism 72. The moving mechanism 72 includes a first rotation element 72 a installed on the floor surface 91 and the second rotation element 72 which is held rotatably by the first rotation element 72 a and holds the arm pedestal 70 rotatably. The rotation element 72 a includes the pedestal 12 and a mid-shaft 13 in place at the distant position from the pedestal 12. The second rotation element 72 includes a horizontal rotation shaft 14.

The pedestal shaft 12 and the mid-shaft 13 are respectively rotation shafts in the perpendicular direction to the floor surface 91. Further, the horizontal rotation shaft 14 is also a rotation shaft in the perpendicular direction to the floor surface 91. Accordingly, the moving mechanism 72 can move horizontally the arm pedestal 70 and the C-arm 30 to the desired position by combining the rotation around the shaft line of the pedestal shaft 12, the rotation around the shaft line of the mid-shaft 13 and the rotation around the shaft line of the horizontal rotation shaft 14.

(Input Receiving Element)

Referring to FIG. 5, an input receiving element 4 a includes the table operation element, the C-ram operation element 4 b, the X-ray detector operation element 4 c and a move mode selection element 4 d.

The table operation element 4 a moves the table 31 while the operator is pressing down the table operation element 4 a under the state in which the move mode selection element 4 d selects the predetermined move mode. Specifically, the table operation element 4 a moves the table 31 to the move target place while the operator is pressing down the table operation element 4 a under the state in which the move target place (position) for the table 31 is predetermined in advance. The operation element 4 a includes e.g., a press button.

The C-arm operation element 4 b moves the C-arm 30 while the operator operates the C-arm operation element 4 b. The C-arm operation element 4 b includes e.g., a lever switch. The inventors set forth the detail of the C-arm operation element 4 b.

The X-ray detector operation element 4 c moves the X-ray detector 2 back and forth in the X-ray irradiation axis direction while the operator operates the X-ray detector operation element 4 c. The X-ray detection operation element 4 c includes e.g., a lever switch. The inventors set forth the detail of the X-ray detector operation element 4 c later.

The move mode selection element 4 d can receive the input of move mode of the imaging equipment component member 3. The move mode selection element 4 d includes e.g., a press button. The move mode of the imaging equipment component member 3 includes such as a femoral approach mode in which the lower leg is imaged, a memory mode in which the C-arm 30 and the table 31 moves to the preset position and a free mode in which the C-arm 30 and the table 31 moves to an arbitrary position. The operator presses down the move mode selection element 4 d for the desired move mode and moves the imaging equipment component member 3 using the desired move mode while operating at least any one element selected from a group consisting of the table operation element 4 a, the C-arm operation element 4 b and the X-ray detector operation element 4 c.

Referring to FIG. 6, the C-arm operation element 4 b includes a first lever element 40, a rotation selection button 41 and a horizontal move selection button 42. The operator tilts the first lever element 40 while the operator is pressing down the rotation selection button 41, so that the operator can tilt the C-arm 30 to the desired angle given by combining CRANIAL or CAUDIAL and RAO or LAO. Further, the operator tilts the first lever element 40 while the operator is pressing down a horizontal moving selection button 42, so that the operator can move the C-arm horizontally.

Further, referring to FIG. 6, the X-ray detector operation element 4 c includes a second lever element 43, an X-ray detector move button 44. The operator tilts the second lever element 43 while the operator is pressing down X-ray detector move button 44, so that the operator can move the X-ray detector 2 back and forth in the X-ray irradiation axis direction.

(Move of the Table and the C-Arm)

Next, referring to FIG. 7A to FIG. 7C, the inventors set forth the move of the C-arm 30 while interlocked with the move of the table 31. The Embodiment illustrated in FIG. 7A to FIG. 7C illustrates the move of the C-arm 30 and the table 31 when the femoral approach mode is selected using the move mode selection element 4 d (referring to FIG. 5).

Referring to FIG. 7A, the control element 60 moves the table 31 in the direction indicated by the arrow sign 81 to image the lower leg of the subject 90 when the femoral approach mode is selected under the condition in which the C-arm 30 is inserted from the head side (X1-direction side) of the subject 90.

At this time, referring to FIG. 7A, the C-arm 30 is in place in the move direction (X-direction) side of the table 31, so that the table 31 cannot be moved under such a condition as-is. If the operator moves the C-arm 30, the table 31 can be moved in the direction indicated by the arrow sign 81, but the number of the operations by the operator increase, and the burden therefor increases. Then according to the femoral approach mode, when the operation conducts to move the table 31, the C-arm 30 moves white interlocked with the move of the table 31. Specifically, referring to FIG. 7B, the C-arm 30 turns in the direction indicated by the arrow sign 82 while interlocked with the move of the table 31. Referring to FIG. 7C, the control element 60 controls the move of the table 31 in the direction indicated by the arrow sign 81 while turning the C-arm 30 until of which position does not interfere the table 31 so that the table 31 moves to the position at which the lower leg of the subject 90 is imaged. In addition, according to the present Embodiment, the control element 60 controls the table moving mechanism 7 a and the C-arm moving mechanism 7 b so that the table 31 and the C-arm 30 moves simultaneously and in parallel.

Here, given the operator does not comprehend that the C-arm 30 moves while interlocked with the move of the table 31 in the femoral approach mode, the C-arm 30 may contact such as operator and technical personnel.

(Information Processing by Control Element)

Then, according to the present Embodiment, the control element 60 controls the information element 5 to inform in advance prior to starting the move of the first imaging equipment component member 3 a (table 31) based on the first operation input when receiving an input of the move mode (femoral approach mode) for moving the second imaging equipment component member 3 b (C-arm 30) while interlocked with the move of the first imaging equipment component member 3 a (table 31) as the second operation input. Specifically, according to the present Embodiment, the control element 60 controls the information element 5 (light emission element 5 a) to inform prior to starting the move of the table 31 as the first imaging equipment component member 3 a when receiving an operation input for moving the table 31 as the first operation input. Specifically, according to the present Embodiment, the control element 60 controls the information element 5 for informing that the C-arm 30 moves when performing the control of the move of the C-arm 30 as the second imaging equipment component member 3 b by the C-arm moving mechanism 7 b while interlocked with the move of the table 31 as the first imaging equipment component 3 a by the table moving mechanism 7 a.

Further, according to the present Embodiment, the control element 60 decides whether the second imaging equipment component member 3 b should be moved or not while interlocked with the move of the first imaging equipment component member 3 a (table 31) without receiving the operation input from the operator for moving the second imaging equipment component member 3 b (C-arm 30). Specifically, the control element 60 decides whether the second imaging equipment component member 3 b (C-arm 30) should be moved while interlocked with the move of the first imaging equipment component member 3 a (table 31) when receiving the second operation input. Here, in the case of that the control element 60 decides whether the second imaging equipment component member 3 b should be moved or not, even if the operator understands the specification in which a plurality of the imaging equipment component members 3 moves respectively while interlocked with one another, the operator cannot be aware of which imaging equipment component member 3 moves while interlocked with one another. Then, according to the present Embodiment, the control element 60 conducts informing using the information element 5 when the second imaging equipment component member 3 b is moved while interlocked with the move of the first imaging equipment component member 3 a (table 31) and does not conduct informing using the information element 5 when the second imaging equipment component member 3 b (C-arm 30) should not be moved while interlocked with the move of the first imaging equipment component member 3 a.

Specifically, when the first imaging equipment component member 3 a (table 31) is moved to the predetermined position based on the first operation input, the control element 60 acquires the present position 50 that is the position before the second imaging equipment component member 3 b (C-arm 30) moves and the target position 51 that is the position after the second imaging equipment component member 3 b (C-arm 30) moves, and also performs the control in which when the present position and the target position are different, the information element 5 informs, and when the present position 50 and the target position 51 are the same, the information element 5 does not inform. In addition, the control element 60 acquires the present position 50 from the potentiometer installed to a driving element (not shown in FIG.) of the C-arm moving mechanism 7 b. Further, the control element 60 acquires the target position 51 from the memory storage element 6 b based on the selected move mode.

(Information Method Using Information Element)

According to the present Embodiment, the control element 60 controls to provide the information as to the move of the second imaging equipment component member 3 b (C-arm 30) by controlling the light emission from the light emission element 5 a (information element 5). According to the present Embodiment, the control element 60 controls to provide the information as to the move of the second imaging equipment component member 3 b by differentiating the light emission aspect of the light emission element 5 a. Specifically, the control element 60 controls as the light emission element 5 a is lighting on while the X-ray fluoroscopic imaging apparatus 100 is working, and when the C-arm 30 moves while interlocked with the move of the table 31, the control for informing is conducted to change the light emission element 5 a from the lighting-on state to the light flashing state.

(Information Processing)

Next, referring to FIG. 8, the inventors set illustrates an information processing in which the control element 60, according to the present Embodiment, initiates the information element 5 to inform that the second imaging equipment component member 3 b (C-arm 30) moves,

At Step 101, the control element 60 decides whether there is the second operation input or not relative to the mode (femoral approach mode) in which the second imaging equipment component member 3 b (C-arm 30) moves while interlocked with the first imaging equipment component member 3 a (table 31). When there is the second operation input, the processing proceeds to Step 102. When there is no second operation input, the control element 60 repeats the processing of Step 101.

At Step 102, the control element 60 acquires the present position 50 of the C-arm 30. In the processing of Step 102, the control element 60 acquires the angle of the C-arm 30 and the position coordinate as the present position 50 of the C-arm 30 from the C-arm moving mechanism 7 b.

At Step 103, the control element 60 acquires the target purpose position 51 of the C-arm 30. In the processing of Step 103, the control element 60 acquires the angle of the C-arm 30 and the position coordinate as the target position 51 of the C-arm 30 from the memory storage element 6 b.

At Step 104, the control element 60 decides whether the present position 50 and the target position 51 are the same or not. When the present position 50 and the target position 51 are the same, the processing proceeds to Step 106. Specifically, when the present position 50 and the target position 51 are the same, the C-arm 30 does not move, so that the control element 60 does not conduct the information element 5 to inform any. When the present position 50 and the target position 51 are not the same, the processing proceeds to Step 105.

At Step 105, the control element 60 conducts to provide the information by the information element 5. Specifically, the control element 60 conduct to provide the information by emitting the light from the information element 5 (light emission element 5 a). Specifically, the control element 60 conducts to provide the information by changing the lighting aspect from the lighting-on state to the light flashing state of the light emission element 5 a.

At the step 106, the control element 60 decides whether there is the first operation input or not. When there is the first operation input, the processing proceeds to Step 107. When there is no operation input, the control element 60 repeats the processing of Step 106.

At Step 107, the control element 60 moves the first imaging equipment component member 3 a (table 31) and the second imaging equipment component member 3 b (C-arm 30) by controlling the table moving mechanism 7 a and the C-arm moving mechanism 7 b.

At Step 108, Specifically, the control element 60 decides whether the second imaging equipment component member 3 b (C-arm 30) moves to the predetermined position or not. When the table 31 and the C-arm 30 moves to the predetermined position, the processing proceeds to Step 109, When the table 31 and the C-arm 30 have not moved to the predetermined position, the processing proceeds to Step 107,

At Step 109, the control element 60 suspends the information element 5 (light emission element 5 a) to provide the information. Then after, the processing ends. In addition, when the present position 50 and the target position 51 are the same, the processing at Step 109 is skipped.

In addition, any one of the processing at Step 102 or the processing at Step 103 may be conducted first.

According to the present Embodiment, practically, the information processing by the control element 60 and the input of the second operation, in which the move mode is selected, are conducted simultaneously. In other words, the control element 60 starts to provide the information in-between from receiving the selection of the move mode to starting the action (receiving the first operation input).

Effect of the Present Embodiment

The following effect can be obtained according to the present Embodiment.

According to the present Embodiment 1, as set forth above, the X-ray fluoroscopic imaging apparatus 100 comprises: a plurality of imaging equipment component members further comprising: an X-ray source 1 that irradiates an X-ray to a subject 90; an X-ray detector 2 that detects the X-ray irradiated from the X-ray source 1; a C-arm 30 that holds the X-ray source 1 and the X-ray detector 2 under the condition facing each other; a table 31 on which the subject 90 is loaded; a display unit 32 that displays an X-ray image 10 of the subject 90; an input receiving element 4 that receives an operation input by an operator an information element 5 that informs a move of any member of the plurality of the imaging equipment component members 3; and a control element 60, wherein the control element performs a control in which the information element 5 informs that a second imaging equipment component member 3 b moves when performing one control of the move of a first imaging equipment component member 3 a based on a first operation input to move the first imaging equipment component member 3 a (table 31) among the plurality of imaging equipment component members 3 and another control of the move of the second imaging equipment component member 3 b (C-arm 30) different from the first imaging equipment component member 3 a of the plurality of the imaging equipment component members 3 while interlocked with the move of the first imaging equipment component member 3 a.

Accordingly, when the second imaging equipment component member 3 b (C-arm 30) moves while interlocked with the move of the first imaging equipment component member 3 a (table 31), the information element 5 informs that the second imaging equipment component member 3 b moves, so that the operator can understand that the second imaging equipment component member 3 b moves even when the operator does not understand in advance with respect to that the second imaging equipment component member 3 b moves while interlocked with the move of the first imaging equipment component member 3 a. Further, even when the X-ray fluoroscopic imaging apparatus 100 identifies the second imaging equipment component 3 b member that moves while interlocked with the first imaging equipment component member 3 a among the plurality of imaging equipment component members 3, the information element 5 can inform that which imaging equipment component member is the second imaging equipment component member 3 b among the plurality of the imaging equipment component members 3, so that the operator who is aware of that a plurality of the imaging equipment component members 3 moves while interlocked with one another can understand which imaging equipment component member 3 moves. As a result, the present invention can provide an X-ray fluoroscopic imaging apparatus 100 that allows an operator or a technician to understand which member of the imaging equipment component members 3 moving while interlocked with the given member of the imaging equipment component members 3 regardless the understanding level as for the equipment specification.

Further, with regard to the present Embodiment, the more effect below can be obtained due to the following structure.

Specifically, according to the present Embodiment and as set forth above, the control element 60 controls the information element 5 to inform in advance prior to starting the move of the first imaging equipment component member 3 a based on the first operation input when receiving an input of the move mode for moving the second imaging equipment component member 3 b (C-arm 30) while interlocked with the move of the first imaging equipment component member 3 a (table 31) as the second operation input. Accordingly, when received the second operation input, the move of the second imaging equipment component member 3 b is informed, so that the move of the second imaging equipment component member 3 b can be informed before the second imaging equipment component member 3 b starts moving. As a result, the operator can assuredly understand that the second imaging equipment component member 3 b moves before the second imaging equipment component member 3 b starts moving.

Further, according to the present Embodiment, as set forth above, the control element 60 decides whether the second imaging equipment component member 3 b (C-arm 30) should be moved or not while interlocked with the move of the first imaging equipment component member 3 a (table 31) when received the second operation input, and also when the second imaging equipment component member 3 b moves while interlocked with the first imaging equipment component member 3 a, the information element 5 informs and whereas, when the second imaging equipment component member 3 b is not moved while interlocked with the first imaging equipment component member 3 a, the information element 5 does not inform. Here, when the information element 5 informs without deciding whether the second imaging equipment component member 3 b moves or not while interlocked with the first imaging equipment component member 3 a, the information element 5 informs even when the second imaging equipment component member 3 b does not move while interlocked with the first imaging equipment component member 3 a. Therefore, the operator may not accurately understand whether the second imaging equipment component member 3 b moves or does not. As set forth above, the informing is conducted when the second imaging equipment component member 3 b moves and not conducted when the second imaging equipment component member 3 b is not moved, so that the move of the second imaging equipment component member 3 b can be informed only when the second imaging equipment component member 3 b moves while interlocked with the first imaging equipment component member 3 a. Therefore, when the information element 5 informs, the operator can understand without fail that the second imaging equipment component member 3 b moves. As a result, it is different from the case in which the information element informs the incident even when the second imaging equipment component member 3 b does not move, so that it can be avoided that the operator confuses.

Further, according to the present Embodiment, as set forth above, when the first imaging equipment component member 3 a (table 31) is moved to the predetermined position based on the first operation input, the control element 60 acquires the present position 50 that is the position before the second imaging equipment component member 3 b (C-arm 30) moves and the target position 51 that is the position after the second imaging equipment component member 3 b moves, and also performs the control in which when the present position 50 and the target position 51 are different, the information element 5 informs, and when the present position 50 and the target position 51 are the same, the information element 5 does not inform. Accordingly, the control element 60 decides whether the present position 50 and the target position 51 are the same or not, so that it can be easily decided whether the information element 5 informs or does not.

Further, according to the present Embodiment as set forth above, the plurality of moving mechanisms 7 that move at least two members of the plurality of the imaging equipment component members 3 are further provided, and the information element 5 is installed to at least one of the second imaging equipment component member 3 b (C-arm 30) and the moving mechanism 7 (C-arm moving mechanism 7 b) that moves the second imaging equipment component member 3 b among the plurality of the moving mechanisms 7. Accordingly, the information element 5 is installed to any one of the second imaging equipment component member 3 b that moves while interlocked with the first imaging equipment component member 3 a (table 31) and the moving mechanism 7 that moves the second imaging equipment component member 3 b, so that the information element 5 can inform near the member that actually moves. As a result, it is different from the structure, e.g., in which a move of the second imaging equipment component member 3 b is displayed on such as a monitor installed as fixed to the predetermined position, and even when the operator is in the position where the operator cannot see such as a monitor, the operator or the technician can understand that the second imaging equipment component member 3 b moves.

Further, according to the present Embodiment as set forth above, the information element 5 is installed to one side and the other side of the moving mechanism 7 (C-arm moving mechanism 7 b) that moves the second imaging equipment component member 3 b (C-arm 30). Accordingly, the information element 5 is installed to both sides of the moving mechanism 7 that moves the second imaging equipment component member 3 b, so that the information from the information element 5 can be understood by the operator and the technician even when the operator is any side of the moving mechanism 7 that moves the second imaging equipment component member 3 b.

Further, according to the present Embodiment as set forth above, the table moving mechanism 7 a that moves the table 31 and the C-arm moving mechanism 7 b that moves the C-arm 30 are further included, and the control element 60 controls the information element 5 for informing that the C-arm 30 moves when conducting the control of the move of the C-arm 30 as the second imaging equipment component member 3 b by the C-arm moving mechanism 7 b while interlocked with the move of the table 31 as the first imaging equipment component 3 a by the table moving mechanism 7 a. Accordingly, the information element 5 informs that the C-arm 30 moves while interlocked with the move of the table 31, so that the structure according to the present Embodiment is desirable relative to the X-ray fluoroscopic imaging apparatus 100, wherein the C-arm 30 moves while interlocked with the move of the table 31.

Further, according to the present Embodiment as set forth above, the information element 5 includes the light emission element 5 a that informs by emitting the light. Therefore, the operator and the technician can easily understand that the second imaging equipment component member 3 b moves, visually by the light emitted from the light emission element 5 a. Further, the move of the second imaging equipment component member 3 b is informed by the light emitted from the light emission element 5 a, which is different from the structure, e.g., in which moving of the second imaging equipment component member 3 b is displayed on such as the display unit 32, so that even when the operator is not accurately understanding the information displayed on the display unit 32, the operator and the technician can intuitively understand that the second imaging equipment component member 3 b moves.

Further, the control element 62 conducts the information element 5 to inform when moving the display unit 32 while interlocked with the move of the C-arm 30 and does not conduct the information element 5 to inform when the display unit 32 does not move while interlocked with the move of the C-arm 30. Specifically, the control element 62 acquires the present position 52 that is the position before the display unit 32 moves and the target position 53 that is the position after the display unit moved and controls the information element 5 to inform when the present position and the target position are different, and whereas when the present position 52 and the target position 53 are the same, the information element 5 does not inform. In addition, the control element 62 acquires the present position 52 from the display moving mechanism 7 c. Further, the control element 62 acquires the target position 53 from the memory storage element 6 b.

Referring to FIG. 11, the X-ray fluoroscopy imaging apparatus 300 according to the alternative Embodiment 2 comprises the information element 5 having a speaker 5 b that outputs the information sound and the computer 36 instead of the computer 6 and is different from the X-ray fluoroscopy imaging apparatus 100 according to the present Embodiment.

The computer 36 according to the alternative Embodiment 2 has a processor 6 d instead of the processor 6 a, so it is different from the computer 6 according to the present Embodiment set forth above. Further, the processor 6 d has a control element 63 instead of the control element 60, so such a point is different from the processor 6 a according to the present Embodiment set forth above.

The control element 63 according to the alternative Embodiment 2 controls the speaker 5 b that outputs the information sound for informing when the second imaging equipment component member 3 b moves while interlocked with the first imaging equipment component member 3 a. The information sound includes a warning message due to an alarm sound and a voice. In addition, according to the alternative Embodiment 2, the control element 63 may apply both the light emission element 5 a and the speaker 5 b to inform or only the speaker 5 b without applying the light emission element 5 a for informing.

Other structural elements according to the alternative Embodiment 2 are the same as the Embodiment as set forth above.

Therefore, the operator and the technician can aurally and easily understand that the second imaging equipment component member 3 b moves by the information sound generated from the speaker 5 b.

Further, other effects according to the alternative Embodiment 2 are the same as the aspect of the present Embodiment as set forth above.

Alternative Embodiments

In addition, the aspects of Embodiments disclosed at this time are examples and not limited thereto in any points. The scope of the present invention is specified in the claims but not in the above description of the aspect of Embodiments and all alternative (alternative examples) are included in the scope of the claims and equivalents thereof.

For example, the control element 60 controls the moves of the C-arm 30 while interlocked with the of the table 31 according to the present Embodiment and the alternative Embodiment 2 as set forth above and the move of the display unit 32 while interlocked with the move of the C-arm 30 according to the alternative Embodiment 1 as set forth above, but the present invention is not limited thereto. For example, the control element may control the moves of the display unit 32 while interlocked with the move of C-arm 30 in case of that the display unit 32 interferes the move of the C-arm 30 when the C-arm moves while interlocked with the move of the table 31. Specifically, the control element may move both the C-arm 30 and the display unit 32 while interlocked with the move of the table 31. When the control element controls both the C-arm and the move of the display unit 32 while interlocked with the move of the table 31, the information element 5 may be installed to both the C-arm 30 and the display unit 32 or both the display unit moving mechanism 7 c and the C-arm moving mechanism 7 b.

Further, the examples illustrate that the first imaging equipment component member 3 a is the table 31 and the second imaging equipment component member 3 b is C-arm 30 according to the present Embodiment and the alternative Embodiment 2 as set forth above and the first imaging equipment component member 3 a is the C-arm 30 and the second imaging equipment component member 3 b is the display unit 32 according to the alternative Embodiment 1, but the present invention is not limited thereto. As long as the member is intentionally moved by the operator, the first imaging equipment component member 3 a can be any member of the C-arm 30, the table 31 and the display unit 32. Further, as long as the member is moved while interlocked with the move of the first imaging equipment component member 3, the second imaging equipment component member 3 b can be any member of the C-arm 30, the table 31 and the display unit 32. In addition, the member that moves in a large area and is heavy is the C-arm 30 among the C-arm 30, the table 31 and the display unit 32. Accordingly, the C-arm 30 among the C-arm 30, the table 31 and the display unit 32 is most affected when the operator or the technician contacts thereto. Therefore, the information element 5 may be installed at least to the C-arm 30 or the C-arm moving mechanism 7 b.

Further, the move mode in the case of moving a plurality of the imaging equipment component members 3 decides which member of the plurality of the imaging equipment component members 3 is the first imaging equipment component member 3 a and which member thereof is the second imaging equipment component member 3 b. Specifically, the C-arm 30, the table 31 and the display mode 32 can be either the first imaging equipment component member 3 a or the second imaging equipment component member 3 b in accordance with the move mode. Therefore, in the structure wherein a likelihood where the first imaging equipment component member 3 a and the second imaging equipment component member 3 b can be changed in accordance with the move mode selected by the operator exists, the information element 5 should be installed to all of the plurality of the imaging equipment component members 3 or the plurality of moving mechanisms 7.

Further, according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, the example of the single plane type wherein the C-arm 30 is one is illustrated, but the present invention is not limited thereto. For example, it can be a biplane type where there are two C-arms 30.

Further, according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, the example wherein the information element 5 informs when the C-arm 30 moves while interlocked with the move of the table 31, but the present invention is not limited thereto. For example, the control element may control the information element 5 for informing when the table 31 moves while interlocked with the move of the C-arm 30. Specifically, it may be acceptable as long as that the control element controls the information element 5 for informing when the second imaging equipment component member 3 b moves while interlocked with the move of the first imaging equipment component 3 a among the plurality of the imaging equipment component members 3. Given such a structure is provided, the operator can be informed relative to the imaging equipment component members 3 that move while interlocked therewith even when the X-ray fluoroscopic imaging apparatus 100 decides the imaging equipment component member 3 to be moved. As a result, it can be understood that which member of the imaging equipment component members 3 moving while interlocked with the predetermined imaging equipment component member 3 without depending on the understanding level of the operator relative to the equipment specification.

Further, the examples illustrate that the information element 5 is installed to the second imaging equipment component member 3 b and informs that the second imaging equipment component member 3 b according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, but the present invention is not limited thereto. For example, the structure may be configured to inform that the second imaging equipment component member 3 b moves and also to install the information element 5 to the first imaging equipment component member 3 a as well and then to allow the information element 5 to inform when the first imaging equipment component member 3 a moves.

Further, according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, the example is illustrated wherein the control element decides whether the second imaging equipment component member 3 b moves while interlocked with the move of the first imaging equipment component member 3 a or not, but the present invention is not limited thereto. For example, the control element may not decide whether the second imaging equipment component member 3 b should be moved while interlocked with the move of the first imaging equipment component member 3 a or not. Specifically, the control element may control the information element 5 for informing based on the second operation input. However, when conducting informing based on the second operation input, the information element 5 may inform even when the second imaging equipment component member 3 b does not move. Given the information element 5 informs the incident even when the second imaging equipment component member 3 b does not move, the operator is confused. Therefore, it is desirable that control element decides whether the second imaging equipment component member 3 b should be moved while interlocked with the move of the first imaging equipment component member 3 a or not.

Further, according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, the example, wherein it is decided whether the information element 5 informs based on the present position and the target position of the second imaging equipment component member 3 b, is illustrated, but the present invention is not limited thereto. For example, the control element may decide whether the information element 5 informs or not based on the first imaging equipment component member 3 a and the position of the second imaging equipment component member 3 b. Specifically, the control element may decide whether the information element 5 informs or not by deciding whether the second imaging equipment component member 3 b should be moved or not based on the position of the first imaging equipment component member 3 a and the position of the second imaging equipment component member 3 b.

Further, according to the present Embodiment and the alternative Embodiments 2, the example wherein the information element 5 is installed to the moving mechanism 7 is illustrated, but the present invention is not limited thereto. The information element 5 may be installed to the second imaging equipment component member 3 b. If the information in which the second imaging equipment component member 3 b moves while interlocked with the move of the first imaging equipment component member 3 a can be provided, the information element 5 can be installed anywhere.

Further, according to the present Embodiment and the alternative Embodiment 1, the example wherein the control element controls to provide the information as to the move of the second imaging equipment component member 3 b by switching the light emission 5 a from lighting-on to light flashing is illustrated, but the present invention is not limited thereto. For example, the control element may control to provide the information as to the move of the second imaging equipment component member 3 b by differentiating the color of the light that the light emission element 5 a outputs. As long as the information as to the move of the second imaging equipment component member 3 b can be provided with the light output from the light emission element 5 a, the aspect for informing is not concerned.

Further, according to the present Embodiment and the alternative Embodiment 1 as set forth above, the examples wherein the information element 5 includes the light emission element 5 a and according to the alternative Embodiment 2, the information element 5 includes the speaker 5 b, but the present invention is not limited thereto. For example, the information element 5 may include a monitor that displays the incident in which the second imaging equipment component member 3 b moves. When the information element 5 includes the monitor, an arrow sign indicating the direction in which the second imaging equipment component member 3 b is about moving can be displayed or the message of the direction in which the second imaging equipment component member 3 b is about moving.

Further, according to the present Embodiment and the alternative Embodiment 2 as set forth above, the example wherein the information element 5 includes the light emission element 5 a that is installed to one side and the other side of the C-arm moving mechanism 7 b, but the present invention is not limited thereto. For example, one light emission element as the information element 5 may be installed to all circumference surface of the C-arm moving mechanism 7 b. Further, one light emission element, as the information element 5, which protrudes on the top surface of the moving mechanism 7 may be equipped. Even when the operators are in both one side and the other side of the moving mechanism 7 and the information in which the second imaging equipment component member 3 b moves while interlocked with the move of the first imaging equipment component member 3 a can be provided, the positioning and number of the light emission element 5 a may not be concerned.

Further, according to the present Embodiment, the alternative Embodiment 1 and the alternative Embodiment 2 as set forth above, the example wherein the control element provides the information when the second imaging equipment component member 3 b is moved while interlocked with the move of the first imaging equipment component member 3 a takes place to the predetermined position is illustrated, but the present invention is not limited thereto.
